To all whom t may concern.'

Be it known that l, JOHN BorsKo, a citizen of the United States, residingat East Akron, in the county of Summit and State of Ohio, have invented new and useful Improvements in Portable Car-Bumpers, of which the fol.- lowing is a specification.

This invention 0relates to a portable car bumper and the object is to provide a device of simple and light construction which may readily be placed in position whenever rcquired, and is especially adapted for use in connection with mine cars, but is also capable of use on railroads in general, for stopping freight or other cars on a siding or the like.

A further object is to provide a device including a frame in which` is resiliently mounted a bumper' for engagement by a wheel of a car, this frame being carried by a base adapted to extend longitudinally along the upper surface of the track and to be retained in position by the weight of the car in connection with which it is to be used.

With the foregoing and other objects in view, the invention consists in the novel construction, combination and arrangement of elements hereinafter describedl and claimed.

In the drawings:

Figure 1 is a View of the device in side elevation and in operative position on a track.

Fig. 2 is a top plan view.

Fig. 3 is a front elevation.

The device herein described may be formed with a casing or frame comprising side members 10 and 12, which if desired may be of substantially triangular formation, and a connecting member 14: provided with a slot 15 in approximately the central portion thereof for the accommodation of a block resiliently mounted and constituting the bumper proper.

The device specified is carried by a base 16 designed to extend longitudinally along the upper surface of the track, the member 14 having connection with the base by means of a tongue 17 riveted or otherwise secured to said base. Downwardly extending ears 18 and 19 are provided for securing flat springs 2O and 21 for contacting with the head and web portion of the rail and serving in part to retain the device in position. The weight of the car on the base 16 prevents longitudinal movement of the device as a whole. rEhe end of the base may be connected with the upper edge portion of member 14, by means of a brace or the like shown at The block 13 carries a plate 23 directly engaged by the wheel of a car and carries a rearwardly extending tongue 2li located between the longitudinal rods 25 and 26 and engaging a cross piece 2T carried by said rods. Each rod is surrounded by a coiled spring, the respective springs being designated 27 and 28 and the rear ends thereof contacting with a cross plate 30 extending between side members 10 and 12 of the frame, and preferably secured in position by rivets passing through a flanged portion 31 carried by the plate last named. The threaded ends of rods 25 and 2G are engaged by nuts shown at 32.

The weight of the mining car or other rolling stock upon the main portion of the base 1G holds the device in proper position, in connection with the action of the spring rail engaging devices above described.

What is claimed is:

1. In a device of the class described, a base portion for contacting with the tread of a rail, a supporting member carried by the base and including a plate portion eX- tending transversely of said base, and pro vided with `an opening therein, a bumper operating within said opening, and'means connected with the base for engaging the web of the rail and including a plurality of offset members passing around the head of the rail.

2. In a device of the class described, a base portion, a plurality of laterally extending members upwardly deflected from the base and constituting the side members of a frame, a plate extending transversely of said members and of the base, said plate being provided with an opening, means connected with the base for engaging the web of a rail, said means including a plurality of resilient members passing around the head of the rail, and a resiliently mounted bumper operating within the opening.

3. In a device of the class described, a base portion, a plurality of resilient members eX- tending downwardly from said base portion, a plurality of members extending upwardly from the base and constituting the side niemopening, a, plurality of rods carried by the bers of a freine, a transversely extending bumper and extending through said stop plate connected With the buse and with the `plate, and resilient devices carried by the side members7 said plate being provided rods and engaging said plate last nfuned. l0
